DMP 500  (260-1252)            Self-Test              Faxback Doc. # 4586

The DMP-500 has a built-in self-test feature which lets you check printing 
quality and general printer operation before you connect the Printer to a 
TRS-80. This is a good time to check that the Print Head is adjusted 
properly (printing is neither too faint or smudging occurs) and if the 
paper is feeding properly.

The Self-Test will last for several minutes. It includes the various print-
er font styles, print widths and intensities, graphics characters.

Before running the Self-Test, however always be sure to load the DMP-500 
with wide paper (15" wide) since the Test prints from one end of the Platen 
to the other. Printing on the Platen can shorten the life of the Print Head.

To run the Self-Test:

1. Plug the Printer into an AC power outlet.
2. Set the ON-LINE/OFF-LINE Switch to OFF-LINE.
3. Press and hold the RESTART Switch.
4. Set the Power ON/OFF Switch to ON.
 
The printer will begin printing all the characters according to the Font 
Style Selection Switch. (Rotary Switch)

5. If the printing is too light, set the Printer off-line and gently move 
the Penetration Control Lever towards the paper. If printing is too dark or 
begins smudging, set the Printer off-line and move the Penetration Control 
Lever away from the paper slightly.
6. Printing will continue until you turn the power OFF.
